Set display order of ListBox control

Hi
I have a ListBox control in my ASP.NET page. After I binding data to this
control, I would like to be able to change this display order of items in
this control. Just like change layout function of my.yahoo.com.
I tried client side approach, yes I can change display order by JavaScript,
but after clicking one of the button the display order will reverse back to
its original status. Because after PostBack, the page will try to render
this control by viewstate again.

I tried server side approach, but looks there is no way to switch two
ListItems programmatically.

Is there anybody who has some good idea?

Thanks!

Dump content of listbox to array, sort array in memory, then clear this
listbox and add listitem from array one by one.

Yep.
That is what my listbox sort routine does.
Just wondering if you came up with something different.

Set DropDownList Items Alignment

Hi

How can I set my dropdownlist Itmes alignement right rether than left?

I bound them from a database??

my code

<asp:DropDownList width="100%" Runat="Server" ID="ddlCollege" DataTextField="CollegeName" Style="text-align: center;" DataValueField="CollegeID" Autopostback="True" OnSelectedIndexChanged="ShowDepartmentsEvents"/>

on the behind code I select values from the database??

Can Someone help??

thanks in advance

Setting style="text-align:right" on the dropdown list will work in Firefox, but I don't think there is any way to do this on Internet Explorer 6.

regards

I'm afraid you cannot do that unless you create you own dropdownlist :(

Hope my suggestion helps.

set multiview active on selection asp:menu item

I have an asp:menu with items in it and a multiview. I want to set the multiview pane depending on which menu item is clicked. Any ideas?

thanks

Hi, andrew

This is for you:

ProtectedSub Menu1_MenuItemClick(ByVal senderAsObject,ByVal eAs MenuEventArgs)Handles Menu1.MenuItemClick

MultiView1.ActiveViewIndex = Int32.Parse(e.Item.Value)

Menu1.Items(0).ImageUrl ="~/Images/HomeDisabled.jpg"

Menu1.Items(1).ImageUrl ="~/Images/ProductsDisabled.jpg"

Menu1.Items(2).ImageUrl ="~/Images/SupportDisabled.jpg"

Menu1.Items(3).ImageUrl ="~/Images/HelpDisabled.jpg"

SelectCase e.Item.Value

Case 0

Menu1.Items(0).ImageUrl ="~/Images/HomeEnabled.jpg"

Case 1

Menu1.Items(1).ImageUrl ="~/Images/ProductsEnabled.jpg"

Case 2

Menu1.Items(2).ImageUrl ="~/Images/SupportEnabled.jpg"

Case 3

Menu1.Items(3).ImageUrl ="~/Images/HelpEnabled.jpg"

EndSelect

EndSub

//////////////////////////////////////

Please tell us if there is something else you have. Thanks

Hope this helps.

Can i use a query string ? e.g. mypage.aspx?multiview=1 because the menu I have is in a masterpage and the multiview is in a content page. I have used your examples to create a working model using that method. Thankyou.

Hi, Andrew

Are you looking this method?

protectedvoidXXX_SelectedIndexChanged(object sender, EventArgs e)
{
MultiView1.ActiveViewIndex = Convert.ToInt32(XXX.SelectedValue);
}

Hope this helps.

It doesnt work because it always says either the menu1 or the multiview1 is undeclared because the menu is on the masterpage and the multiview on the content page.

If I have a url of

e.gg

http://www.abtecnet.com/services.aspx?view=1

http://www.abtecnet.com/services.aspx?view=2

etc

Then cant I get the query string with Response.Write(Request.QueryString("view"))

And then somehow use that number to set the active index of the multiview?

Cheers

Andrew

If Ive got

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim viewstring As String
viewstring = Request.QueryString("view")

servicemultiview.setactiveindex()
End Sub

how do I set the active index to the value of the query string based on above?

Thanks

Andrew

Done it now

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim viewstring As Int32
viewstring = Request.QueryString("view")
servicemultiview.ActiveViewIndex = viewstring
End Sub

set selected value declaratively to dropdownlist

Hi,
I just wonder if there is a way to set a selected item in dropdown list
which items are retreived from database without touching c# code ?
I mean, i have in gridview, in edit mode one dropdownlist which
selected value should be the same as a label text from normal view mode
<EditItemTemplate>
<asp:DropDownList ID="ddlGrdvFrequency" runat="server"
DataTextField="Frequency"
DataValueField="FrequencyId"
DataSourceID="SqlDataSourceMembershipFrequency" />
</EditItemTemplate>
I was looking for sth like SelectedIndex, but intellisense did not give
me any prompt for it. I use now C# code in databound event for gridview
to set this item selected, but ...is there a way of not using this ?
thanks for any promptsHi,
You can set the selectedvalue property on the dropdownlist as follows
<EditItemTemplate>
<asp:DropDownList runat="server" ID="ddl"
DataSourceID="SqlDataSource2"
DataValueField="ProductID"
DataTextField="ProductName" SelectedValue='<%# Bind("ProductID")
%>'></asp:DropDownList>
</EditItemTemplate>

hi podi,
unfortunately the SelectedIndex cannot be set declaratively, it is a compile
error. i'm just wondering how you could know in advance with a databound
list which one to select?
an alternative would be to sort the datasource so that the one you want to
select is the first record, then it will be selected by default when the
list is databound.
i think the databound event is the correct (and best) place to achieve your
task.
i hope this helps
